Gents, Regarding cooling air for the cockpit, I have the same concern.
At this point, I have only 15 hrs on the ship, each one flown on a sunny
SoCal day. I needed good vent air whether the OAT was 40f or 80f. Rear air is
NACA vent connected like Van's RV8 plan using wing air. This works good. I
can reach around from my seat and flip the eyeball open or shut.
On first flights, my front eyeball blew hot air no matter what. It was
rigged using air from top of engine baffle to Van's mechanical mix valve (cold
side) and muff air (warm side, same valve). It was obviously leaking hot air no
matter how the mix valve was set... I disconnected the heat muff (removed
scat hose) and taped over the mix valve inlet hot side, so it is mechanically
locked to receive only the cool baffle air. It works fine now. Air is cool
and fresh at flying speeds. Haven't put a T- probe there yet to compare
with rear pit air.
Conclusion: Tapping cockpit air from top baffle is OK and effective.
I also need to tap some of that front air for radio cooling. When I reach
up under the panel in flight, those buggers are hot-hot after a while. Can't
be good. My front eyeball is located such that I can direct air up towards
the stack... that helps some but is only a temp solution. I was going to put
in a NACA scoop to vent the instrument section but your current list
discussion has me wondering.

#32 air from both sources mentioned seem to be REAL close in temp into the
office. One under the wing and the other right side of the fuse. !?!?!?!?!?!
